Figure 2: 3D-matrigel culture promoted neurite outgrowth of SGN explants. (a) The planar characteristics of SGN explants, the number , the length , and the area of neurites, were measured. (b) SGN explant as the illustration for number, length, and area of neurites. (c) The schematic of the height of neurites in SGN explant. (d) SGN explant as the illustration for the height of neurites. (e–h) Quantifications of the average number, length, height, and area of neurites. , , and .
